From my cursory knowledge, it does appear that Jeffersonian Democracy, let alone the Republican viewpoint, seems to marginalize the central government's role to permit some flexibility in exercising civil and political rights (note the opposition to the federal government) while, in adherence--and if we analyze from the viewpoint of--Jefferson's own political views, amidst the emphasis on cultural simplicity reflecting the rural character of much of the land (which translated, in particular, his distaste for affected decorum), universal education, etc.

Of course, that would seem to be the virtual end, though my inquiry is at least focused on how you would certainly define it. (Note that I have not mentioned, for example, how Jefferson believed that the farmer was a powerful and autonomous political figure, able to operate politically without due interference of the mob pressures and local sympathies found in the cities or local workshops, or his other views defining the government that was certainly influenced by the Enlightenment (Locke). [And that is to ignore other beliefs in regards to rationalism that shaped his perception of public education, and so forth.]

The general point is, and excuse my relatively pedantic surmise there, lol, that the overarching framework. So much can be said of a system as a response to the mandated act of condensing, in the form of a single definition, the underlying essence; I have not, as one can clearly see, condensed, let alone identify the underlying impulse that drives such a view to full fruition, though I have perhaps hinted of such (uninhibited popular virtue and exercise of due civil rights?). Perhaps, in regards and in reference to your knowledge of "Jeffersoniasm," what would be the essence of his views, and in particular, what is your critique of the system overall considering your political ideologies and likings?
